My apologies if this question has already been asked, but so far I haven't seen any information that matches my particular situation.

Am I eligible for an F-4 visa? My story below...

I was born in the US to Korean parents. They had Korean citizenship at the time and have never changed to US citizenship. My family never put me on the Hojuk. I have had US citizenship all my life. I never went through any formal process to renounce Korean citizenship.

And lastly, it's a long story but not 100% sure if my parents have a greencard. Just putting this out there since I'm not sure if it matters or not in my situation.
